FIELD OF THE INVENTION

The present invention relates to a bicycle carry rack, and more particularly, to a securing device for positioning a bicycle frame on the bicycle carry rack.

BACKGROUND OF THE INVENTION

The conventional bicycle carry racks are designed to be connected to the rear end of the car and is able to carry bicycles with the car. There are two types of carry rack available, one of which includes grooves in which the bicycle frames are secured, and the other type is a trailer which is moved with the car and the bicycles are located in the trailer. The conventional bicycle carry rack has a connection member so as to be connected with the hitch, or the bicycle carry rack directly attached to the rear end of the car by hooks and tightening strips. There are many tightening strips are used to secure the bicycle to the carry rack, most of the tightening strips are made by plastic which has a head on one end and the other end of the tightening strip extends through the head. Multiple teeth are formed on the tightening strip and one of the teeth is engaged with a locking tooth in the head so as to tighten the bicycle frame, such as the top tube, to the carry rack.

However, the tightening strip is mounted to outside of the bicycle frame and most of the bicycle frames and the carry rack are composed by round tubes, so that the contact area between the bicycle frames and the carry rack is small. Therefore, the bicycles on the carry rack easily shake when the car moves along a rugged road. The plastic-made tightening strips do not have proper flexibility to match the curvatures of the bicycle frames and the carry rack. This causes the bicycles to be loosened during transportation.

When dismounting the bicycles from the carry rack, the plastic-made tightening strips have to be cut, and this causes waste and the user has to prepare scissors or knifes. Besides, when the bicycles are secured to the carry rack again, new tightening strips are required.

The present invention intends to provide a securing device for positioning a bicycle frame on the bicycle carry rack so as to improve the shortcomings mentioned above.
